This colored Chandra X-ray Observatory image (inset) shows Westerlund 2 in context with the Spitzer infrared observation (black & white). Westerlund 2 is a young star cluster with an estimated age of about one or two million years. Until recently little was known about this cluster because it is heavily obscured by dust and gas. However, using infrared and X-ray observations to overcome this obscuration, Westerlund 2 has become regarded as one of the most interesting star clusters in the Milky W...

On October 9, 1604, sky watchers -- including astronomer Johannes Kepler, spotted a "new star" in the western sky, rivaling the brilliance of nearby planets. "Kepler's supernova" was the last exploding supernova seen in our Milky Way galaxy. Observers used only their eyes to study it, because the telescope was not yet invented. Now, astronomers have utilized NASA's three Great Observatories to analyze the supernova remnant in infrared, optical and X-ray light...

Animation of Supernova Explosion. MPEG When a massive star explodes, its outer layers are hurtled out into space at thousands of miles an hour and a neutron star is left behind. In the case of Puppis A, astronomers think the explosion that created this supernova remnant kicked the neutron star into motion, eventually ejecting this cosmic cannonball from the Milky Way galaxy.
